PORTLAND -- A Portland State University professor, along Silverton astronaut Don Pettit and two mathematicians have developed a zero-gravity coffee cup.

“The low-g cup exploits an interior corner, which combined with favorable wetting, lets surface tension replace the role of gravity so you can kind of drink normally,” said PSU mechanical engineering professor Mark Weislogel. “It’s pretty simple. Works well for champagne too.”

Pettit has tested the product in space. NASA will be using the cup during future space explorations.

Students at PSU's Maseeh School of Engineering recently completed a 40-day, non-stop series of experiments with ISS crews on fluid systems of spacecraft.
